The study effectively highlights the significance of biochar properties like quinone functional groups and elemental composition (e.g., nitrogen, nickel, and zinc) in facilitating reductive debromination. It’s intriguing to see such strong correlations emerge from the analysis. However, I’m curious; did the authors explore or consider potential mechanistic studies, such as real-time electron transfer measurements or spectroscopic techniques, to directly observe the role of these functional groups or elements during debromination? Additionally, given the environmental emphasis, how do you envision scaling this approach while managing potential challenges like metal leaching or biochar longevity in diverse remediation scenarios?
